IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent- No. 206,634, dated July 30, 1878; application filed May 21, 1878.

To all whom it may concern:

Be it known that I, CHARLES E. STELLER, of the city of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Oombined Sash Adjuster, Lift, and Lock; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this speeifiation.

Figure 1 of the accompanying drawing represents an elevation of my invention as applied to a window. Fig. 2 is a detached view of the device. Fig. 3 is a view of the baseplate; and Fi 4, the securing-plate.

The object of my invention is to provide an improved window-sash adjuster, lift, and lock combined, which locks the sash automatically when closed, is unlocked preparatory to opening by simply pressing upward upon the sashlift, and automatically adjusts the sash at any point where released instantaneously without danger of the sash falling, which device is more particularly applicable to be used in railroadcars and upon all sash not suspended by counterweights, and which also serves to prevent loose sash from rattling in their casings, all of which is further explained by reference to the aecompanyin g drawing, in which- A represents the whidow-frame. l) is the sash to which my device is applied. 0 is a base-plate. It is secured to the sash by screws 1), to which base-plate the other parts are socured by rivet E, and around which rivet they perform a partial revolution when locking and unlocking the sash. The lift F, adjuster G, and the locking-arm II are all constructed in one piece of metal in such a manner that they may be cast in the required shape without inachine-work, and the patterns readily drawn from the sand in forming the molds for the same.

The adjuster G consists of asolid block of rubber, I, which is inserted from the back side against the projecting points J, which points, together with the shoulders K, hold the rubber friction-block I firmly and securely in its place, when aplate, L, is secured against the back side of the rubber by a rivet, which is inserted through the hole M, and is secured in a corresponding hole in the plate, thus walling in the rubber block on all except the front surface, which surface forms the friction-bearing of the adjuster, whose walls prevent the block from being pressed out of place or shape or becoming flattened by its pressure against the casings.

The arm II is a continual ion of the adjuster G. It is provided with hook N, which engages automatically with the catch 0 when the sash is closed, and thus locks the window and prevents it from being raised from the outside. The sash is unlocked and raised by upward pressure upon the lift F, which movement throws back the hook N from the catch 0, and at the same time draws back the rubber friction-bearing from the casing. The lift F is constructed to nicely fit the finger, and serves in a convenient manner the double offiee of lift for raising the sash as well as for unlocking and adjusting the same.

There is a spiral spring, t, surrounding the rivetE,between the base-plate C and the head of the adjuster G, which is secured at one end to the base-plate C in groove P, and at the other end to the head of the adjuster G, which spring is arranged to throw the adjuster to ward the casing, whereby it is both secured instantaneously at any point, as soon as the lift is released, and the catch thrown in looking position when the sash is closed. The lower end of the base-plate D serves as a check to the arm II, which arm is constructed so as to engage therewith as the sash is raised, thus preventing the adjuster from turning farther than is necessary to release the locking-hook and free the friction-bearing from the casin Fig. 2 is a modification of the same device, which is more particularly adapted to be used upon the upper sash, in which place there is no occasion for using the catch N, and it and the arm ll are dispensed with, and the liftF is so modified and diminished in size that the under sash can pass it when the sashes are moved past each other. In all other respects the fi gures represent the same invention.

When the described device is applied to one side onlyof the upper sash, the opposite side of the same is liable to sag, and may be supported by the deviee S, which is arranged to engage in a notch provided for it in the casing.

Having thus described my invention, what I claim as new, and desire to secure by Let ters latent, is-- 1. The adjuster(l,eonsisting in the peeuliar arrangement of the rubber triction-bloek I, as secured in a reeess by shoulders l ,pro ieeting points J, plate L, and rivet M, all substantially as and for the purpose specified.

2. The combination of the device eonsisting of lift I adjuster G, and armII,provided with hook N, with the catch 0, all substantially as and for the purpose speritied.

3. As a new article of manufacture, a combined window-sash adjuster, lift, and lock, eonsisting' in lift 1 arm H,pr0vided with hook N, adjuster l provided with rubber friction-bearin gs I, as seeured thereto by shoulder K, projecting point J, plate L, and rivet M, baseplate 1), and catch 0, all substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own 1 afiix my signature in presence of two witnesses.

CHARLES E. STllLLl'lll.
